Abstract:
This scanning electron microscopic study of eight toothbrushes for children has shown differences in quality and quantity of the rounding of bristle ends. While four products which were examined for the first time were partially deficient, the preparation of the other toothbrushes had clearly improved in comparison to previous products. Quotas of acceptable end rounding of the bristles varied considerably between 14.3% and 90.2%. Welding of bristle bundles at their base into the head of the toothbrush offers hygienic advantages.
